ADJUSTABLE SUPPORT FOR BEDBOTTOMS.

Application filed November 2, 1923. Serial No. 672,302.

tom equipped therewith being properly sup-' ported in bedsteads of different widths.

in the accompanying drawings,

Figure l is a transverse sectional view of one side of a bed bottom equipped with our invention Fig. 2 is a broken side view of the parts illustrated in Fig. l;

l ig. 3 is a top plan View of the same; and

Fig. at is a perspective view of a part of-a bed bottom equipped with another form of the invention. p

In the drawings A, represents the longitudinal or side rail of a bedstead, which may be of any usual or approved construction. The bed bottom frame, which likewise may be of any desired or approved construction, comprises longitudinal frame pieces 2 and transverse frame pieces 3, these being arranged in the same or different levels as the character of the bed bottom may require. Upon the bed bottom frame are supported spiral springs 4, which are tied together in any approved way and united to a top marginal frame 5. In order to provide a bed bottom frame such as described with supports adapted to engage with the bedstead, and adjustable so as to fit bedsteads of different widths, we have devised the mechanism which we will now describe and which constitutes the present'invention.

The numeral 6 represents angular hangers formed with flat horizontally disposed upper members that are adapted to rest upon the side rails A of the bedstead. Each hanger is carried by a bar 7 which is supported so as to be transverse to the bed frame and to stand vertically on edge. A single carrying bar for each hanger may be used, as represented in Figs. 1 to 3, or a plurality of such bars as shown in Fig. 4.

Referring to Figs. 1 to 3, 8 indicates a frame in which the carrying bar 7 is adjustably supported. The frame is preferably of metal and angular in shape having the two uprights 9, 9 and a top connecting piece 10. The upright 9 is rigidly secured to one of the longitudinal pieces 2 of the bed bottom frame, and is slotted, as indicated at 11, to permit the bar 7 to be passed through the upright, the length of the slot being little greater than the width of the bar. The inner upright 9 is rigidly secured to a connecting piece 12 uniting two of the transverse frame pieces 3. It is also slotted for the passage of the bar 7, as indicated at 13. The under edge of the bar 7 is notched as indicated at let to provide an adjustable engagement between the bar 7 and the upright 9 that will prevent lateral movement of the former. We prefer that the upright supports 9, 9 should be provided with a plurality of'slots to receive the bar 7, these beingarranged one above the other, and-have represented each upright as having formed in it'a second slot, designated, respectively, 11 and. 18. 15 indicates a cotter pin that passes through the adjustable carrying bar 7 near its inner end and serves as a means for preventing the bar from being entirely drawn out of its supports.

As many of these adjustable supports may be used with each bed bottom as maybe required. Preferably four are employed, one near each corner of the bed bottom frame, but more maybe used, if desired. It is entirely feasible to make the supports along one side of the bed bottom rigid and pro,- vide the opposite side only with adjustable supports made according to our invention.

The manner ofusing our invention is apparent, and sufiice it to say that after the bars 7 have been adjusted so that the hangers 6 will properly engage with the siderails of the bedstead, and the bed frame has been set "in the latter, each adjustable support will assume the position indicated in Fig. '1, from which it will be observed that the upper edge of the bar 7 bears against the upright 9 at the upper end of the slot 11, while its $5? lower, notched, edge engages with the upright 9 at the lower edge of the slot 13. The weight of the bed bottom maintains the "parts in this position and insures that they shall be thus held against accidental displacement. Should it be desired to adjust a bar and the hanger which it carries, it is only necessary to lift the inner end thereof sufficiently to disengage the notched edge thereof from the upright 9, after which it maybe moved longitudinally, either inwardly or outwardly, to the desired extent.

By making the supporting frames 8 of sufficient height and providing them with a plurality of slots to receive the bars 7, we make provision for supporting the bed bottom at various heights.

In the form of our invention illustrated in Fig. 4 the supporting hanger 6 is carried by a pair of bars 7, which pass through a slotted plate 16 carried by a bar 17 depending from the bed bottom frame. The supporting bars 7 carry at their inner ends a saddle 18 adapted to ride upon a transverse bar 19 which may be suitably supported, as for instance, at its outer end, by the depending bar 17. The hanger 6 and its supporting bars, in the form of our invention just described, are adjustable transversely of the bed frame, the bars 7 sliding in the slotted plate 16 and the saddle 18 sliding upon the bar 19 when such adjustments are made. While both forms of the invention illustrated possess in common novel features of construction and operation, each has some features of advantage incident to its peculiar construction. For general purposes, however, we prefer the form of invention shown in Figs. 1-8, as it is more economical to construct and is positive in operation, the notches 1 L preventing any accidental movements of parts after they have been properly adjusted.

In each form of the invention the supporting bar may be considered a lever of the third order in which power is applied through the hanger The wei.ghtthe bed bottom frame and its load-rests on the bar where, in one case, the upright 9 engages therewith, and in the other case, where the plate 16 engages with the bars, and the fulcrum is where the inner portion of the bar has adjustable engagement with a supporting partin one instance, the upright 9, and in another, the bar 19.

It is apparent that the adjustable supports which we have described, and which have been devised primarily for use in connection with bed bottoms, are equally adapted to support other objects than bed bottoms, in or upon other frames than bed-= steads; and therefore when we use either of the terms bed bottom or bedstead in the claims hereof, they are employed in a typical sense and are intended to include not only these parts but others which are the equivalentsthereof so far as they co-operate with the adjustable supporting devices constituting our invention in the same manner as do these specified parts.

What we claim is:

1. The combination with a bed bottom frame, of adjustable means for supporting the same in a bedstead consisting of an upwardly extending frame rigidly secured to the bed bottom frame and formed of a pair of narrow vertical bars spaced apart and united at their upper ends by a connecting piece, the bars having formed in them narrow vertical slots, a vertically disposed supporting bar passing through the slots in the bars and being held against turning thereby, one edge of the supporting bar being notched, the notches adapted to selectively engage one of the slotted bars at the end of one of the slots to prevent it from being accidentally moved longitudinally, and a bracket carried at the outer end of the slotted bar formed with a flat horizontally disposed member adapted to rest upon the side rail of a bedstead.

2. The combination with a bed bottom frame, of adjustable supporting means therefor, including a supporting hanger adapted to engage with a rail of a bedstead, an adjustable bar carrying the hanger, a pair of vertically arranged supporting bars carried by the frame, each bar having a plurality of slots, one above the other, adapted to receive and hold vertically on edge the adjustable bar, which bar is adapted to be supported in either set of slots to permit the bed bottom to be supported at different heights and being longitudinally adjustable to properly engage with bedstead frames of different widths.
